[SOLVED] alias with sudo: Password request malfunction

Question

Okay so here are two cool little system-maintenance related aliases, as suggested by "pacman tips" Wiki:
Show dirs not owned by any package:
alias pacman-disowned-dirs="comm -23 <(sudo find / \( -path '/dev' -o -path '/sys' -o -path '/run' -o -path '/tmp' -o -path '/mnt' -o -path '/srv' -o -path '/proc' -o -path '/boot' -o -path '/home' -o -path '/root' -o -path '/media' -o -path '/var/lib/pacman' -o -path '/var/cache/pacman' \) -prune -o -type d -print | sed 's/\([^/]\)$/\1\//' | sort -u) <(pacman -Qlq | sort -u)"
Show files not owned by any package:
alias pacman-disowned-files="comm -23 <(sudo find / \( -path '/dev' -o -path '/sys' -o -path '/run' -o -path '/tmp' -o -path '/mnt' -o -path '/srv' -o -path '/proc' -o -path '/boot' -o -path '/home' -o -path '/root' -o -path '/media' -o -path '/var/lib/pacman' -o -path '/var/cache/pacman' \) -prune -o -type f -print | sort -u) <(pacman -Qlq | sort -u)"
typically I edit those into my "/etc/bash.bashrc" instead of "~/.bashrc", but there's no difference there. The thing is, when I invoke this alias,
as regular user, it promptly requests [sudo] password, as it should, but after a brief moment the console returns to normal, there's no time for to even input the password, like this:
[danilo@dandelion ~]$ pacman-disowned-dirs
[sudo] password for danilo:
[danilo@dandelion ~]$
PS: If my password is still cached, it will work normally (my timeout is set to 30 min).
here's my "/etc/bash.bashrc" at any rate:
# /etc/bash.bashrc
## If not running interactively, don't do anything ##
# [[ $- != *i* ]] && return
## Prompt display configurations ##
set_prompt () {
local last_command=$? # Must come first!
PS1='\[\e[1;33m\]'
if [[ $last_command != 0 ]]; then
PS1+='$?'
fi
if [[ $EUID == 0 ]]; then
PS1+='\[\e[1;31m\][\u@\h \W]\$\[\e[0m\] '
else
PS1+='\[\e[1;34m\][\u@\h \W]\$\[\e[0m\] '
fi
PROMPT_COMMAND='set_prompt'
PS2='> '
PS3='> '
PS4='+ '
## Original default configs ##
case ${TERM} in
xterm*|rxvt*|Eterm|aterm|kterm|gnome*)
PROMPT_COMMAND=${PROMPT_COMMAND:+$PROMPT_COMMAND; }'printf "\033]0;%s@%s:%s\007" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/\~}"'
screen)
PROMPT_COMMAND=${PROMPT_COMMAND:+$PROMPT_COMMAND; }'printf "\033_%s@%s:%s\033\\" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/\~}"'
esac

Answer 1

You'd suppose it would work, but no, same error... Perhaps it traces back to some other configuration file...
By the way, the second command, I didn't paste it correctly; There's no "&&" before the pacman query part of the command. Fixing the post now...
Well, anyways, I believe I got'em working, I appended a useless command that requires elevation AND works properly, like this:
alias pacman-disowned-dirs="sudo true && comm -23 <(sudo find / \( -path '/dev' -o -path '/sys' -o -path '/run' -o -path '/tmp' -o -path '/mnt' -o -path '/srv' -o -path '/proc' -o -path '/boot' -o -path '/home' -o -path '/root' -o -path '/media' -o -path '/var/lib/pacman' -o -path '/var/cache/pacman' \) -prune -o -type d -print | sed 's/\([^/]\)$/\1\//' | sort -u) <(pacman -Qlq | sort -u)"
And:
alias pacman-disowned-files="sudo true && comm -23 <(sudo find / \( -path '/dev' -o -path '/sys' -o -path '/run' -o -path '/tmp' -o -path '/mnt' -o -path '/srv' -o -path '/proc' -o -path '/boot' -o -path '/home' -o -path '/root' -o -path '/media' -o -path '/var/lib/pacman' -o -path '/var/cache/pacman' \) -prune -o -type f -print | sort -u) <(pacman -Qlq | sort -u)"
...Still, it's a r@t workaround, not a proper solution, so I'll ask to not mark this as solved yet. Maybe someone can backtrack this properly.
Thank you, for the quick reply, much appreciated.
